WIRE-BOUND-BOX MACHINE.

7 Specification of Letters Patent. Patented M 15 1921 Application filed December 29, 1916. Serial No. 139,509.

To all whom it may concern:

Be it known that 1, CHARLES H. BOM BAPDIE, a citizen of the United States, and resident of South Bend, county of St. Joseph, State of Indiana, have invented an Improvement in l/Vire Bound Box Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In the operation of machines for use in making wire-bound boxes, box blanks or sectlons, it is desirable to fasten together the box material, a. g. cleats and side material, and thebinding wires thereto in desired relation to the edges of the work or otherwise and to avoid fastenings at the box joints. Among other objects my invention is intended to provide a machine of the general class referred to which, acting continuously, will position the successive fastening devices in any desired relation. For

instance, in producing a wirebound box by progressively stapling binding wire to assembled cleats and side material it is desirable to place those staples nearest the box corners in definite relation thereto and iii the box is of the type known as a crate the spacing of the staples throughout the side of the box will be irregular because of the use of spaced slats.

My invention will be best understood by the description of an illustrative embodi-' ment thereof shown in the accompanying drawings wherein Figure 1 is a side elevation of one end of a box blank machine embodying my invention.

Fig. 2 is a section on the line 2-2 0" Fig. 1.

Box blank machines in general consist of a stapler head or battery of staple-forming and driving mechanisms and a work holder,

the two being moved relatively step by step.

so that the staples will be driven at various points along the work dependent upon the length of the steps.

In. the present embodiment of the inven tion I show (Fig. 2) a machine embodying a fixed stapler head and a movable work holder. The stapler head is mounted in suitable frame- 1, as shown, having the fixed cross-bar 3 and a reciprocating cross-head 5, which together carry the stapling mechanisms 7 shown diagrammatically in Fig. 2.

The cross-head 5 is reciprocated by pitman 9 and eccentr cs 11 on the main drive shaft 13, and each time that it descends a staple is driven into the work beneath the crossbar 3. In Fig. l the eccentric 11 has been broken away to more clearly show the structure in which my invention more particularly resides.

Referring now more particularly to Fig.

1, the work is moved beneath the stapler head on a work holder comprising cleat receiving chains 15, trained over sheaves 17 and supported on the longitudinal channel bars 19. But one set of sheaves is shown in the figure as the general construction of mechanism so far described is well known in the art and no difliculty will be found in understanding the operation of the parts mentioned. 7

In the example of the invention illustrated the chains are advanced step by step by a reciprocable driver arranged to impart motion on movement in one direction. Such a driver 1s exemplified by the pawl lever 21 cooperating with ratchet wheel 23 on the axle of the sheaves 17. The'pawl lever 21 is effect this a rod 29 extends from pawl lever V 21 and may be guided in suitablebearings 31 on the frame of the machine. Slidable upon this rod isa block 33 to whichthe lever 25 is connected and a collar 35 is attached "to the rod and cooperates with this block,

as shown in Fig. 1, so as to draw the rod to the right in the clockwise strokeofthe actuator lever. driving stroke of the lever 25 the block 33 would slide freely to the let-t on rod 29 were it not for force-transferring means next to be described which act to transmit more or less of the motion of the actuator lever 25 to the pawl-carrying lever 21.

In the embodiment of the invention illustrated the force-transferring means takes the form of an abutment 37 on the rod-29 and a cooperating, oppositely disposed abut- On the counter clockwise or ment on the sliding block 33. Intermediary f0rcetransferring members are presented between these abutments to delimit the amount of lost motion of the block on the rod.

In Fig. 1 a short headed rod or pin 41 mounted in a carrier, here shown as a wheel 43, is in position between the two abutments 37 and 39 and it is apparent that as the abutment 39 moves to the left it will push to the left the pin 41 and through it the abutment 37 and so move the pawl carrying lever 21. The stroke of the block 33 is designed to carry the abutment 39 into close proximity to the face of wheel 43 and therefore the movement of the pin 41 and consequently of the pawl carrying lever 21 will depend upon the projecting length of the pin. For example, if the pin 41 shown at the lower part of the wheel in Fig. 1 were in position between the abutments instead of: the pin 41 it is obvious that a much shorter left hand stroke would be imparted to the rod 29 and consequently the ratchet wheel 23 would be moved through fewer teeth and a shorter step imparted to the work carrier 15. In other words, the rod and sleeve with their cooperating abutments and a set of pins 41 carried by the wheel form a connection of variable effective length between the actuator lever and the pawl lever 21.

In the present embodiment of the invention the wheel 43 is designed as a pattern mechanism to determine the length of the successive steps of the work carrier. Iteferring particularly to Fig. 2, it will be seen that the rim of the wheel is pierced with a series of holes to accommodate any suitable number of pins 41 and that if the wheel is rotated these pins will be presented. in succession between the abutments 37 and 39. To effect this the wheel is urged in a counter clockwise direction (viewing Fig. 2) by a suitable frictional transmission device 45 -which ordinarily would rotate it at a com- I the friction drive so as to present successive pins between the abutments upon the successive strokes of the fixed throw actuator. In the present instance. this means takes the form of a spring pressed latch 47 which extends into the path of the pins. as shown in Fig. 2, and holds one of them in position be tween the abutments. To release the latch the block has a nose portion 49 provided with a beveled end 51 arranged to cooperate with roll on the latch. As the sleeve completes its stroke to the left; viewing Fig. 1, the roll will, ride up the beveled surface 51 and the latch 47 will be moved clear of pin 41 and the wheel 43 will be released to the action of the frictional. driving mechanism 45 as the sleeve commences its return stroke. At the same time the latch 47 will drop down into position to engage the next pin which is set in the rim of the wheel and the latter is held in proper position to transfer motion from the abutment 39 to the abutment 37.

Viewing Fig. 2, it will be seen that I provide a cam member 55 cooperating with the left hand ends of the pins 41 for repositioning them with their heads in contact with the left hand side of the wheel ready for presentation a second time when the wheel has made a revolution between the abutments.

The manner of using the machine can readily be understood from the description of its structure. A suitable number of pins corresponding in length to the length of the successive steps between staples on the desired blank are selected and placed in position in the wheel 43 with the first in contact with the latch 47. As the main power shaft is rotated the stapler head will be reciprocated and in alternation the carrier pins will be moved through a series of steps whose length'will depend directly upon the length of pins in the pattern mechanism. The spacing of successive staples may there fore be controlled as desired. \Vhen one box blank is finished the friction drive of the wheel will provide for turning it to a zero position with the first pin of the series in contact with the latch 47. This feature is very desirable as it is possible to run the machine continuously and not be troubled about making adjustments for successive blanks. At the same time a large pattern member or wheel 43 may be used with provision for accommodation of a number of pins equal to the number of staples in the largest size of blank and need not be changed for smaller blanks wherein fewer staples are required.

The machine is positive in its action and has a strong and simple mechanism. No reliance is placed on springs and even the spring of the latch 47 might be dispensed with as gravity would sufiice to return the latch to position.

I have described in considerable detail the embodiment of the invention illustrated in the accompanying drawing wherein I have shown it as applied to a wirebound box ma chine of that type wherein a work-holder in the form of endless chains is moved relatively to a fixed stapling mechanism. It will be understood, however,' that my purpose in making such a minute description was to render my invention more readily comprehended and that it is not limited to the details of structure shown and described. On the contrary, the structure and the principles thereof may be widely varied without departing from the spirit of the invention.
